A Push–Pull Network with Infinite Supply of Work

Anat Kopzon, Yoni Nazarathy, Gideon Weiss
2009 Queueing systems  
We consider a two-node multiclass queueing network with two types of jobs moving through two servers in opposite directions, and there is infinite supply of work of both types.  ...  We compare this network with the Kumar-Seidman-Rybko-Stolyar network, in which there are two random streams of arriving jobs rather than infinite supply of work.  ...  It differs from our Push-Pull network in that, instead of infinite supply of work, it has exogenous arrivals of jobs of type i at rate α i , i = 1, 2.  ...

Positive Harris Recurrence and Diffusion Scale Analysis of a Push Pull Queueing Network

Yoni Nazarathy, Gideon Weiss
2008 Proceedings of the 3rd International Conference on Performance Evaluation Methodologies and Tools  
Unlike the KSRS network, we can find policies under which our push pull network works at full utilization, with both servers busy at all times, and without being congested.  ...  It is similar to the Kumar-Seidman Rybko-Stolyar (KSRS) multi-class queueing network, with the distinction that instead of random arrivals, there is an infinite supply of jobs of both types.  ...  Guo and Zhang [13] have adapted Meyn and Down's ideas to a reentrant line with infinite supply of work where the policy is to give lowest priority to the activity with the infinite supply.  ...

Non-Existence of Stabilizing Policies for the Critical Push-Pull Network and Generalizations [article]

Yoni Nazarathy, Leonardo Rojas-Nandayapa, Thomas S. Salisbury
2013 arXiv   pre-print
We settle this conjecture and devise a general sufficient condition for non-stabilizability of queueing networks which is based on a linear martingale and further applies to generalizations of the push-pull  ...  The push-pull queueing network is a simple example in which servers either serve jobs or generate new arrivals.  ...  A Push-Pull Ring with an Even Number of Servers Similar to the push-pull network (the special case with M = 2), a non-idling policy is a mapping P : S → {push, pull} M , with the restriction that the pull  ...

Using Metaheuristic and Fuzzy System for the Optimization of Material Pull in a Push-Pull Flow Logistics Network

Afshin Mehrsai, Hamid-Reza Karimi, Klaus-Dieter Thoben, Bernd Scholz-Reiter

Stability of multi-class queueing networks with infinite virtual queues

2013 Queueing systems  
We generalize the standard multi-class queueing network model by allowing both standard queues and infinite virtual queues which have infinite supply of work.  ...  We pose the general problem of finding policies which allow some of the nodes of the network to work with full utilization, and yet keep all the standard queues in the system stable.  ...  The bulk of the work of Yoni Nazarathy on this paper was while he was affiliated with EURANDOM/Eindhoven University of Technology and partly supported by the same grant.  ...

Asymmetry between pushing and pulling for crawling cells

Pierre Recho, Lev Truskinovsky
2013 Physical Review E  
To study the inherent asymmetry between active pushing and pulling we model a crawling acto-myosin cell extract as a 1D layer of active gel subjected to external forces.  ...  Instead, pulling is driven by protrusion only at small values of the pulling force and it is replaced by contraction when the pulling force is sufficiently large.  ...  Kruse, A. Mogilner and two anonymous reviewers for helpful comments. The work of P.R. was supported by the Monge Doctoral Fellowship from Ecole Polytechnique  ...
